C0287 Code: Meaning, Causes, and Symptoms | OBD2 Codes
C0287 – EBCM Receives Invalid Torque Signals
C0287 Possible Symptoms
Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)
C0287 Possible Causes
Faulty Electronic Brake Control Module (EBCM),Electronic Brake Control Module (EBCM) harness is open or shorted,Electronic Brake Control Module (EBCM) circuit poor electrical connection
The Electronic Brake Control Module (EBCM) supplies 5 VDC to the Powertrain Control Module (PCM) on the delivered torque signal circuit. The PCM toggles this voltage to ground in order to create the delivered torque signal at the EBCM. A signal with a frequency of 128 Hz +/- 5 percent and a duty cycle of 25-95 percent is a valid delivered torque signal. The percentage of the duty cycle is proportionate to the percentage of delivered torque.
